Prices shown in currencies other than USA Dollars are estimates based on current exchange rates. We will charge your credit card in USA Dollars on the day your order is shipped, and the conversion to your local currency will be done at the prevailing rate by your credit card issuer.

Shipments outside the USA are declared as “bike parts” for customs purposes and will include the actual amount paid for merchandise and shipping. Jenson USA will not mark your parcel as a “gift”, declare a value lower than the actual price paid, or otherwise prepare false customs information.

I converted my mountain bike for a road tour (weird, I know, but stick with me) and used this stem extension to create a higher steerer for fitting butterfly handlebars. I obviously wouldn't use it for downhill mountain biking, but it clamped tight and secure and I had no problem with it at all for many days. The vertical screw that adjust the tension of the fork is inside the lower part, so the top cap is only a dustcap. That allows you to clamp a stem at any height of the extension tube without the use of spacers, which i found convenient for fitting the bike. An added bonus is that it's inexpensive.
